摘要
根据一种改进的模态综合法，本文简化了其子结构刚度矩阵和质量矩阵，并编制了微机程序，用这一方法分析了３００型采煤机摇臂壳体的动态特性。
The stiffness matrix and mass matrix of. the substructrues are. simplified on the basis Of an improved method of the component model synthesis, and the microcomputer programs are drawn up. The method has been used to analyse the dynamic charcteristics of the rocking arm shell of coal machinery type 300.
